Application & Dosage
Applications
1. Boiler Water Treatment
Cyclohexylamine is used in neutralizing amine formulations for steam boiler condensate treatment.
It helps neutralize carbonic acid and reduce corrosion caused by acidic condensate.
2. Steam Condensate Corrosion Control
Cyclohexylamine is used to maintain suitable pH in steam condensate systems, helping protect compatible steam pipelines, condensate return lines and equipment against acid-related corrosion.
3. Corrosion Inhibitor Manufacturing
Used as a raw material in selected industrial corrosion inhibitor formulations, including neutralizing amine and vapor-phase corrosion inhibitor systems.
4. Rubber Chemical Manufacturing
An important chemical intermediate for manufacturing certain rubber vulcanization accelerators used in tyres, rubber hoses, conveyor belts and industrial rubber products.
5. Chemical Intermediate
Used in the production of specialty organic chemicals, industrial additives and chemical synthesis intermediates.
6. Industrial pH Adjustment
Used in selected industrial processes requiring an alkaline organic amine for neutralization or pH control.
Cyclohexylamine is also utilized as corrosion inhibitor. Cyclohexylamine is used as an intermediate for the various synthesis :
Herbicides (e.g. S-ethyl N-ethyl cyclohexyl thiocarbamate)
Antioxidants & vulcanization accelerator (e.g. N-cyclohexyl 2-benzothiazole sulfenamide)
Mucolytics
Broncodialators (e.g. bromhexine HCl)
Analgesic agents
Additive for prevention of CO2
Corrosion inhibitor in steam pipelines and boilers
Urethane chain stopper
Artificial sweetener such as cyclamates.
Cyclohexylamine in Boiler Condensate Treatment
During steam generation, dissolved carbon dioxide may travel with the steam and form carbonic acid when the steam condenses.
This acid can lower condensate pH and contribute to corrosion.
Cyclohexylamine helps neutralize the acidity:
By maintaining appropriate condensate pH, Cyclohexylamine helps reduce acid-related corrosion and supports the long-term reliability of compatible steam systems.
Dosage: The required dosage depends on condensate pH, carbon dioxide loading, steam system design and operating conditions. Dosage must be established through a suitable boiler treatment programme. Direct dosing of concentrated Cyclohexylamine without proper engineering controls is not recommended.
